firmware from the modem, then he will set up the host PC for XMODEM receive and the
downloader FLM will begin to send the existing firmware from the flash memory to the host
PC.
Procedure::
1. Install in the modem a flash memory programmed with the modem firmware or a blank flash
memory.
2. Put the uploader FLM and downloader FLM files and the new modem firmware file (e.g.,
XmUL003.s37, XmDL003.s37, and 206s4712.S37) in an appropriate directory on the
computer's hard disk.
3. Configure the communications application program for a DTE rate of between 9600 bps and
115200 bps and RTS/CTS flow control.
4. Check the modem for response by typing AT.
5. Initiate the download process using the AT** command. The Download flash code…"
message appears upon issuing the AT** command.
6. Perform an ASCII transfer of the FLM file (e.g., XmUL003.s37 for uploading new firmware
to the modem or XmDL003.s37 for downloading existing firmware from the modem) from
the host computer to the modem RAM using an industry standard communications software
or an equivalent process (ensure that all ASCII translation or pacing is turned off).
7. After the FLM has been loaded, if uploading new firmware to the modem, perform an
XMODEM upload of the new modem firmware hex file (e.g., 206s4712.S37) from the host
computer to the modem RAM using an industry standard communications software or an
equivalent process. If downloading existing firmware from the modem, using an industry
standard communications software or equivalent, put the host PC in XMODEM receive
mode.
